UNITED STATES LEO G. STRANSKY, OF PUKWANA, SOUTH DAKOTA.

VACUUIVLFEED TANK FOR AUTOMOBILES.

Application filed September 22, 1922. Serial No. 589,779.

To all whmu. it? may conccm:

Be it known that I. Lno G. STRANSKY, a citizen of the United States, residing at Pukwana, in the county oi Ernie and State of South Dakota, have invented certain new and useful Improvements in Vacuum-Feed Tanks for Automobiles, oi which the itollowing is a specification.

This invention has reference to attachmerits for vacuum feed tanks for automobiles and its object is to provide for the regulation of the air teed to the intake side of the engine so as to prevent the breaking of the vacuum in the vacuum tank where little suction is necessary to draw the easeline from the supply tank to the vacuum tank.

The invent-ion comprises a- T-shaped casting with a cent'al stem, ending in a male thread and a. cross pipe ending at the ends in valve structures with the central pipe and the terminal valves sloping downward ly and each valve including a ball memberin a casing having" a range of movement to and from the terminal part of the valves and capable oi. rising against a valve seat slotted to permit the incomplete closure of the seat and to drop onto an opening which may be closed by the ball valve.

The hole in the middle or male threaded. projection has a passage much lar er than the. two in the valve sleeves comnined so that the main suction is in the center male threaded projection. Since the greater amount oi? suction is through this center male threaded projection this will cause proper working of the vacuum feed at all speeds of the engine. I

By plugging the female connection in this casting and attaching an elbow to the mid die male coniuj-rtion. the Stilt vaporizer may he used on the Ford and Chevrolet types of min s and other cars. trucks and tractors. while the vapm'izer may he at. .ched to the vacuum teed tank of such cars as the .iDorlg -r; itudehaker and liuick.

Tillie invention will he hest understood from a consideration of the following do tailed desc ipt-ion taken in connection wilih.

invention expressed in. the appended. claims.

In the drawings Figure 1 is a perspective view or the invention applied to vacuum teed tanks of the Buick or other makes ct automobiles.

Fig. 2 is a front elevatirm of the vaporizer attachment.

Fig. 3 is a central vertical section therethrough.

l ig. 4 is a view similar to Fig. 2 but modilied for automobiles oi. the Ford and Chevrolet type of automobiles.

Fig. 5 is a section on the line 5-5 of F l. Referring to the drawings, particularly to Fig. 1, there is shown a vacuum tank 1 such as is employed, for instance, on the Buick automobile and may be taken as typical oi. other vacuum tanks.

In connection with the vacuum tank, there is provided a vaporizer 2 shown separately in Figs. 2 and 8, and on a larger scale than and separate from the vacuum tank.

The vaporizer comprises a casting $3 in the form of a pipe having depending necks i and 3 at the ends and. at an intermediate point another neck 6 also depending and of somewhat greater length than the necks land 5. here is a duct '2' extending throughout the length oi? the pipe 3 and joining: other ducts 8, 9 and 10 in the necks i, 5 and (3.

Each neck 8 and i) te ninatcs at the lower end in a valve seat ll provided with notches or recesses 12. i i, respectiwiv. at the lower ends.

Applied 'o the necks -l and i are clos or valve containersl ;c and lo, 'es mctiveiv. screwed onto the +2; and 5. The i tainer l proviiv i the lower end with a perioration it: and the container 15 is provided at th l i ,ower end with another pi-nu'iora- 'tion ll, which may he oii larger size than lill'i Perforation it. The closures or containers let. are (.Bttt'i]. provided with milled hands it? permitting the manipulation oi these containers hv fingers of the l'lljtl...;1... hand it so iilesired. or they may be operated h means oi a suitable tool.

The neck 6 is nnewhat longer than the necks 4c and 5 and terminates at the lower end in a 1n ale screw continuation 1.9 which is at tached to a male connection on top and near center oil? vacuum tank 1.. The neck 25 has a female connection. to which an elbow is applied and to which is screwed one end of pipe 21, usually of flexible metal ype to mately joined by coupling to a a 23 designed to enter the engine main in Fig. l.

The upper end oi the neck 6 provided with an internally threaded extension to receive a screw plug :26 when the attachment is used with the Ford or Chemolet automobiles.

Lodged in each container it and 15 is a ball valve 97 adapted to the seat ll and capable of moving into and out of the seat, being prevented from being lost by the respective container lei or 15.

In attaching the vaporizer to vacuum teed tanks, but little suction is necessary to draw the gasoline from the rear or supply tank to the vacuum tank. wherefore the ball valves cause sullicient re ancc to allow the engine to draw sniiicient air out of the vacuum tank and draw the gasoline from the rear tank.

In operation. the suction is mainly through the neck 6 and this suction is modilied by the presence oi. the necks el and :i as further modified by the irescncc oi the valves 27 and the lay-passes about the alvcs to the valve seats with the air intakes through the passages 16 and 17.

The several passages are so proportioned as to cause proper working (it the 'HCCHDII feed at all speeds of the engine.

By plugging the female connect-ion 25 and. attaching the elbow 20 to the middle male connection, the same vaporizer may be used on the Ford, Chevrolet. and many other cars, trucks and tractors, by drilling and thread ing a hole in intake manifold.

The vaporizer is especially adapted to they removal of carbon from within the engine. To do this place a cup under the sleeve with the small opening. Then after the engine warms up open the throttle about halt-way and pour water into the cup. This will be sucked up into the engine and it has been found in practice that this water will form steamin the cylinders. which loosens and removes every particle of carbon from the Oil.

gine. It this procedure is repeated once every day for three or four days. while the engine is warm. the engine Will be kept clean. The engine should be run fast when the water is oured into the cup for otherwise there is a, liability of k' lng' the engine. About one half gallon or water is used every time. Hot water is a little better than cold water and two heaping tablespoons full of baking soda. added to a quart of water will hasten the reinoval oi the carbon.
